April 17, 1956 J. SYLVAN WINDOW ASSEMBLY 2 Sheets-Sheet 2 Filed Dec. 23 1950 JNVENTOR. aosifix/ 6 r4 1044/ BY awzn a. fia/wau United States Patent 2,742,118 WINDOW Assam iner Joseph Sylvan, Berkley, Mich. Application December 2;, 1959, Serial No. 203,453 4 Claims. (Cl. 189--72) This invention relates to an improved window assembly.

An object is to provide a window assembly including complementary jaznb members for upper and lower slidable sash adapted to be secured to the jamb portions of a stationary window frame such as a wood frame to provide an improved jamb and guide channel assembly adapted to receive upper and lower slidable sash therein.

Another object is to provide complementary upper and lower guide channels for upper and lower slid-able sash which guide channels may be readily secured in place upon the jarnb portions of a stationary window frame provided with window stops toremovably receive and support upper and lower sash for slidable movement.

A meritorious feature is that the guide channels are adapted to be so mounted within the window frame so as to exhibit upper guide channels extending alongside of corresponding lateral faces of the window stops and secured thereto, and lower guide channels extending alone and secured to the window stops and seated upon the opposed faces of such stops offset inwardly within the window frame of the upper guide channels.

Eachpair of guide channels is adapted to readily removably receive its slidable sash. The lower pair of guide channels exhibit corresponding channel Walls offset laterally from corresponding channel Walls of the upper guide channels so as to serve to support the upper sash when disposed in the elevated position within the upper guide channels. The lower guide channels exhibit other channel walls bent outwardly at their upper ends so as to serve as supports for a superposed third sash of the assembly elevated above the lower sash thereof to a nonuse position.

A meritorious feature of the upper channels is that each guide channel comprises two channel-shaped elements one of which is disposed inverted within the other to serve as a slide rail for a slidable sash received within such other.

A meritorious feature of the lower sash guide channels is that each comprises a strip of material bent to form a channel guide, one side wall of which extends below the bottom wall of the channel guide and is doubled upon itself forming a two thickness supporting flange extending below the bottom of the channel guide.

Another meritorious feature of the assembly is the provision of a sill member L-shaped in cross-section and having the ends of the upright leg of the Lextcnding beyond the ends of the horizontalleg thereof andwhich sill member is slidably disposed within the guide channels for support therebetween. This sill member includes a crown element channel-shaped in cross-section adapted to be telescoped over the upright leg of the l. section to frictionally grip the same to maintain telescoped positions thereupon.

Other objects, advantages and meritorious features will more fully appear from the following specification, claims and accompanying drawings, wherein:

This invention is shown in association with a stationary window frame of the wood type comprising a sill portion and a header portion 22 connected by two complementary opposed j'arnb portions 2-4. The two jamb portions are provided with two complementary window stop portions 26 shown in Figures 3 and 4 as integral therewith but commonly formed as separate strips secured thereto.

This invention comprises complementary upper sash guide channels, con'iplementary lower sash guide channels, a header member a. sill member secured within the frame as herein described. The header member is an angular metal section 28 shown in Figures 2 and '5 as secured to the header 22 of the frame to overlap the top rail of the upper sash U. There are two complementary upper guide channels 3%) shown particularly in Figures 2, 4, 5 and 7. Each of these upper guide channels is a channel-shaped structure secured by screws 32 or the like to a window stop These screws 32 are shown as extending through the side walls .of the guide channel.

The complete guide channel includes, in addition, an inner channel-shaped element 3.4 which is shown in Figures 4, 5, 6 and 7 as disposed inverted within the channel-shaped element 38 to form a slide rail for the upper sash. Such internal channel 34 is held in place by the screws 32 as shown in Fig. 4. An upper sash U is slidably disposed within the upper guide channels. This sash is shown as comprising a glass pane provided with a metal frame 36 which frame maybe an extruded H section as illustrated. The bottom rail of the sash may be provided with a ledge all as shown in Figure 5, which ledge is adapted to serve as a hand-grip portion. The side rails of the upper sash bear against the inverted channel slide members '34 within the upper guide channels.

Two complementary lower sash guide channels 42 are provided as shown particularly in Figures. 2, 3 and 7. Each lower guide channel may be formed from a strip of material bent into a cross sectional shape as shownparticularly in Figure 3. Such shape exhibits a. channel portion 43 and a supporting flange portion 44.. The flange portion is secured by screws 46 or. the like to the outer lateral face of the window stop 26. This double thickness flange 44isformed by one side wall of'the channel 43 ex.- tendingbelow the bottom of the channel and being folded upon itself as shown in Figure 3. The channel portion proper 43 of this guide channel member 42 seats upon that face of the window stop which is opposed to the complementary window stop as shown in Figure 3.

As shown in Figures 3 and 4 thelower pair of sash guide channels are otfset laterally inwardly of the window from the upper pair of sash guide channels. This lower pair of sash guide channels is also olfset toward upper end of such outer side wall is indicated by the number 45 in Figure and it will be noted that in such figure the bottom rail 38 of the upper sash is seated upon the upper end of such side wall and held in the elevated position with the upper guide channels thereby.

It will be understood that the guide channels are made of aluminum or some other flexible, resilient material. They normally resiliently frictionally grip the slidable sash disposed therewithin and have a permitted flexibility so as to permit ready insertion into and easy movement of the sash within the channel. It is also possible to readily insert the upper sash U within the upper guide channels and to move it to the elevated position where it will shift laterally slightly to seat upon the upper ends of the outer side walls of the lower sash guide channels as hereinabove described.

The lower sash L is readily slidably received within the upper ends of the lower sash guide channels. Such lower sash is of less width than the upper sash U. Such lower sash L has a frame which may be formed of an extruded metal H section as described in connection with the upper sash. The upper ends of the inner side walls of the two lower guide channels are bent as at 52 away from the outer side walls as shown particularly in Figures 5, 6 and 7. These upper ends serve as supports for a screen indicated as S in Figure 5 or other sash element. When the screen is so supported it is in an out-of-use position overlying the upper sash. A clip 54 may be secured to the window jamb as shown in Figure 1 to hold such screen in place between the window jambs above the lower sash.

The sill member 55 of the assembly, shown in Figure 10, comprises an L-shaped cross-section having a horizontal leg 56 doubled upon itself as shown in Figure 10 and an upright leg 58 doubled upon itself as shown in such figure. The two ends of the upright leg 58 project beyond the two ends of the horizontal leg. These two ends of the upright leg are adapted to be slidably received within the lower sash guide channels 42 as shown in Figure 9.

A channel-shaped crown section 60 is telescoped over the upright leg 58 as shown in Figures 9 and 10 and is adjustable vertically thereover to different telescoped positions to provide an even sill support for the lower slidable sash. This sill member is readily receivable between the lower sash guide channels and assembled therebetween. Each of the slidable sash is readily receivable within the guide channels of the assembly and removable therefrom. The screen S is readily received in place in lieu of the lower sash between the lower sash guide rails and the lower sash may thereupon be stored in the outof-use position occupied by the screen in Figure 5.
